SIGNAL v o John H. Ishmael, Spearfish, S. Dak. Application August 25.1938, serial No. 226,799

1 Claim.

This invention appertains to new and useful improvements in direction signals especially adapted for use on automobiles.

The principal object of the'present invention is to provide a direction signal which can be readadvantages of the invention will become apparent 1 to the reader of the following specification.

In the drawings: Figure l represents a fragmentary front elevational view of an automobile showing the signal mounted on the topi thereof.

Fig. 2 is a side elevational View of the signal.

Fig. 3 is an enlarged fragmentaryvertical sectional View through the` signal and diagrammatically showing the pipe lines to the intake manifold and valve.

Fig. 4 is a fragmentary -detailed sectional vie on line 4-4 of Fig. 3.

Referring'to the drawings wherein like numerals designate like parts, it can be seen in Fig. 1, that numeral 5 represents the usual automobile windshield while numeral 5 denotesthe automobile top. The signal is generally referredl to by numeral 'I and is mounted on the central portion of the top 5 where it is visible from all angles. The signal 'I includes the housing or casing 8 which partly depends through the top 6 and which has the laterally disposed plate or wing members 9 9 at its lower portion for attachment to the slats or frame-Work construction of the top 6. Extending laterally from the casing 8 are the cylinders Ill-il in which the pistons I2--I3 respectively, are operative. These pistons I2--I3 are connected by the rod I4 having the rack gear I5 at its intermediate portion. This rack gear meshes with the mutilated gear I 6. 'I'he shaft I1 carries the large mutilated gear I8 which meshes with the smaller mutilated gear I 9' on the 'shaft 2U. The shaft 20 has the leg portion 2I lof the semaphore casing 22 secured thereto. The casing 22 is hollow as denoted in Fig. 4 and has transparent or translucent tubes 23 disposed therethrough at closed spaced intervals. These tubes have rounded end portions which protrude beyond opposite sides of the semaphore casing. Each tubular member 23 is .provided with an electric or incandescent bulb 24at its mid point (Cl. 116-f39) while its end portions formr compartments for containing glycerine 25 or other similar material which will glisten in daylight.

The outer end of the semaphore casing 23` is bifurcated as at 2B, and contains the transparent or transluscent triangular formation 21 in which a light can be positioned.

For equalizing the position of the semaphore to a straight vertical section, coiled compressible springs 28-28 extend from pins 29 on the gear I8 to anchoring members 30 on the inside of the casing 8.

As shown in Fig. 3, numeral 3| represents the valve member which can be located adjacent the drvers seat or on the instrument board, (not shown). This valve `consists of the baseplate 32 with the shelf 33 secured thereto. On the base plate 32 are thevtwo stops34-35 for limiting the .action of the `handle 36, which handle is secured to the shaft 3l for actuating the rotor 38. This rotor 38 is provided with slots 39-40 therein.

'Ihe tube 4I `from the cylinder II communicates with the groove or slot 39 at the point 42, while the tube 43 from the cylinder VIll communicates with the channel 40 as at 44. Numerals 45-46 represent bleeder vents in the shell 33. The numeral 4'I is a common suction portion from which extends the tube 48 to the conductor .49 on thel intake manifold 50 of the engine.

It can now` be seen that in the event the signal is to be pointed toward the right, the handle 3B is moved toward the right and against the stop 34 in Fig. 3 which brings into communication the port 4l and port 42 by way of the channel 39. Thus the vsuction effect of the engine isextended to the cylinder I and draws the piston I3 toward the left in the cylinder I I. This action also takes place in reverse order when the handle 36 is moved toward the left in Fig. 3.

It is to -be understood, that this signal apparatus as shown in Fig. 1 is to be located on top of the vehicleapproximately midway between the front and rear thereof so that it will be visible through the slot 53 can be actuated longitudinally of theslot 53 for reciprocating the rack bar I4.

While thev foregoing specification sets` forth the invention in specific terms, it is to be understood that numerous changes in the shape,

size and materials may be resorted to without de` parting from the spirit and scope of the invention vas claimed hereinafter.

10 said pistons and extending through the lower portion of the housing, a semaphore, a gear for operating the semaphore, a pinion carried by the gear, a rack on the bar meshing with the pinion, protuberances on` the side of the gear and spring members extending from the protuberances and being connected to the inner side of the housing for centralizing the position of the gear and semaphore.
